| titleOfInvention | Trivalent gold cyanogen-less gold plating solution and its application based on the coordination of heterocycle Alkaloid |
| abstract | The invention discloses the trivalent gold cyanogen-less gold plating solution being coordinated based on heterocycle Alkaloid and its application, electroplate liquid includes trivalent gold salt, complexant, pH buffer, mould inhibitor and additive.Wherein, to provide auric gold chloride as main salt, using heterocycle Alkaloid as complexant, using Anhydrous potassium carbonate and dipotassium hydrogen phosphate trihydrate mixture as pH buffer, using sodium tetraborate or sodium benzoate or formaldehyde as mould inhibitor, using the organic matter of sulfur-bearing as additive.Cyanogen-less gold liquid gold salt convenient sources of the invention, comprehensive performance are prominent；Plating solution has preferable covering power；Anti- diadochy is strong, and fresh plating nickel sheet, which is placed in 3min in plating solution, will not occur replacing layer gold phenomenon；In 0.1~1.2A/dm 2 Under broad current density, obtained Gold plated Layer with nickel, copper substrate caking power is good, brightness is high and color is uniformly golden yellow；In addition, also having plating solution preparation simple, craft of gilding facilitates controllable feature. |
